Interior insulated cornice for use under low-heel roof trusses?
Has anyone found, used, or developed an interior insulated air-seal cornice for the wall to ceiling connection below a “low heel” truss eave condition that does not accommodate full attic insulation thickness?
The interior cornice in this condition would be a substitute for a spray-foam wedge in the framing where the truss bears on the wall. The wall is existing 1973 2×4 construction with a double top plate, so the wall insulation terminates at the underside of the top plate. How much of a condensation issue would it be to insulate with an interior cornice, lowering the winter temperature of the wall’s top plate?
